摘　　要：根据现场和模型试验测试结果,通过深入研究锚杆单元与围岩单元的相互作用关系,建立能够真实地反映大变形巷道锚杆力学特性(应变软化特性)的锚杆单元模型,应用VC++编程,将其成功地应用于工程实践.In light of the results achieved from the insite monitoring and laboratory experiments, through studying systematically on interactive relationship between bolt elements and rocks elements, the model of bolt element was set up. It can indicate the bolt's behaviors (i. e. strain-soften characteristics) in the roadway with large deformation. VC++ was successfully applied in practice works.
